Using data obtained by the gamma-ray imager on board the Astro-rivelatore Gamma a Immagini Leggero (AGILE) satellite, we systematically searched for transient gamma-ray sources above 100 MeV that are temporally and spatially coincident with 10 recent high-energy neutrino IceCube events. We found three AGILE candidate sources that can be considered possible counterparts to neutrino events. Detecting three gamma-ray/neutrino associations out of 10 IceCube events is shown to be unlikely due to a chance coincidence. One of the sources is related to the BL Lac source TXS 0506+056. For the other two AGILE gamma-ray sources there are no obvious known counterparts, and both Galactic and extragalactic origin should be considered.STAMPAenArticle10.3847/1538-4357/aaf1c02-s2.0-85060234518000456063900017https://iopscience.iop.org/article/10.3847/1538-4357/aaf1c02019ApJ...870..136LFIS/01 - FISICA SPERIMENTALEERC sectors::Physical Sciences and Engineering
